Buck to doe ratio can be fixed two ways, one of those ways (kill more does) reduces the total number of deer you have, and in the long run will reduce bucks and does on an almost equal scale. The other ( kill fewer bucks) increases the total number of deer you have, and in long run will increase bucks and does on an almost equal scale. If you have to many deer see a browse line in late winter, never see does with twins, no fat on deer when you skin them, weights of deer killed are below what the average should be for your area. Use the first method, it is also the easiest to get people to go along with cause you get to kill stuff. If none of this exist use the second method, upside is you won’t need many bullets but you will see more deer. I am not a never kill a doe guy I will and do kill 1-2 a year. If you only shoot bucks 4.5 years old or older and kill no more does than you do bucks you won’t have to worry about, and you will will be just fine in the long run. It is virtually impossible for the ratio to be more than 3 does to 1 buck when deer season starts. This ain’t rocket science.
